Would a girl text extremely dry if they like a guy?

I like this girl and I was scared to say anything because he’s my coworkers daughter but the coworker is 50 and she’s my age (21). I just said to him yesterday after he said his daughters think I’m a good looking guy. I asked if he’d be ok if I liked the daughter and he said yes I’m a good guy and all that. Then he said she likes me too but it confuses me because every text I send gets responsed to in a week or 2 and when she texts back it’s a “lol” I’m like there’s no way she finds me attractive in the slightest. Am I thinking too far into the texting?
